' To all whom it may concern:

Be it known that LJoHn E. HANsoN, a citizen of the United States, and a resident of St. Paul, in the county of'R-amsey and State of Minnesota, have invented certain new and useful Improvements in Carpet-Beaters, of which the following is a specification.

This invention relates to carpet heaters, and an Object of the invention is to provide 7 a carpet beater including a plurality of piv otally mounted beaters or beating members which are normally held in a carpet engaging position by spiral springs and to embody in the beater structure, means operable by the travel of the beater over a carpet to raise the beater out of engagement with the carpet and against the tension of said springs, for a limited time after which the action of the raising means is released and the'beaters are quickly brought into engagement with the carpet by the contractin action of the springs. orespecifically, the invention compre-. hends the provision of a carpet beater including a pair of supporting wheels'and. a crank shaft connecting the said wheels, which" crank shaft is rotated through the medium of a plurality of gears one of which meshes with teeth formed upon the inner periphery of the supporting wheels, to rotate thecrank shaft in a uniform direction upon rotation of the supporting wheels in either'a forward or backward direction and -which crank shaft engages the pivoted beaters for moving them against the tension of their operating springs. 'j 3 Other objects of this invention will appear in'the following detailed description,

taken in connection with the accompanying and corresponding parts, 1' indicates the.

handle of the improved carpet beater which is connected by means of arms 2 and 3 to plates 4 and 5 respectively. These plates 4 and 5 have the inner section 6 of the supporting wheels 7 and 8 rigidly connected thereto.- The inner sections 6 of the sup porting wheels 7 and 8 are disk-shaped and have central hubs or collars 9 spun or otherwise suitably formed thereon and these hubs form bearings for the hub 10 of the outer portions 11 of the wheels 7 and 8, allowing the outer portions 11 of the wheel to rotate about these hubs 9. The outer portions 11 comprise disks having annular flanges 12 formed about their periphery, the

free inner edges of which fianges engage the periphery of the inner disks 6. The plates 4 and 5are pivotally connected near their lower ends'as shown at 13 to the disks 6 to permit the plates to be swung upon these pivots, as indicated in dotted lines in Fig. 3 of the drawings for moving the gears 14 into engagement with the internal'teeth 15 of the outer-rotatable section 11 ofthe wheels 7 and 8 when the handle 1 is pushed forwardly. The gears 14 are rotatably carried by stub shafts 16 which are carried by the plates f and 5 respectively and they travel through arcuate slots '17 formed in the stationary inner disks 6 'ofthe wheel structure. The gears 14: mesh with the gears 18 which are carried by stub shafts 19. These stub shafts 19are also carried'by the plates 4 and 5 respectively and travel in slots 20 formed in the inner stationary plates or disks 6 of the wheel structures upon pivotal movement ofwthe plates 4 and 5. Supportingarms 21' are connected to the stub shafts'19 and they carry at their upper ends, the end of a crank shaft 22. The

crank shaft 22 travels in slots 23 formed in the stationary inner disks 6 of the wheels 7 and 8 during pivotal movement of the plates 4 and 5. The crank shaft'22 has gears-24 mounted thereon which mesh with the gears 18. Whenthe handle 1 is drawn rearwardly, for moving the carpet beater backwardly, the gears 18 will be moved into engagement with the internal teeth 15, and thus the crankshaft will be rotated in a uniform direction upon movement of the carpet beater in eithera'forward or backward direction and when the handle, and the plates 4 and 5 are locked in a neutral position as shown in dot and dash lines in Fig. 3,both sets "of the gears 14and-18will be held out of engagement with the teeth 15 and the beater may be propelled without'rotating the crank shaft 22. The gears 14 and 18 and the plates land rare-held in a neutral position, by means of a lock or brace 26 which ispivotally carried the inner disks 6 of the wheel 7 and rests in a notcli thereof engage the upper surfaces of the short end 31 ofthe heaters 32, rocking these heaters upon their. pivots. The heaters 32 are pivotally mounted by means of forming coils 33 intermediate theirends, upon a rod 34' which extends fromone disk 6 to the other and they have their outer ends flattened as shown at 35 for beating engagement with a carpet, rug or'the like. Collars 36 are carried by the heaters inwardly of their pivots, and contractile spiral springs 37 are connected to these collars and to the overhanging flange 38 of a guard plate 39. This guard plate 39 is attached, by means of suitable attachingmeans indicated at 4C0, to the disks 6 and it is provided with slots indi-- cated at ll in which the inner charge operating end of the heaters 32 travel during theirpivotal movement under depressing action of the rim portion of the crank shaft 22 and upward movement under the contracting action. of the springs 37. This upward movement of the operating end of the beater under contractingaction of the springs 37 will cause the flattened beating end 35 there of to be sharply forced downwardly into'engagement with a carpet, rug or the like for heating the same.

Guide. plates 48 are carriedby the disks 6 and engage the outer 'surfacesof the plates 4: and 5 for holdingthese-spaced plates properly spaced from the disks 6 and also for forming support for the plates during their pivotalmovement.

Generically, the operation iof' the heater is as follows: WVhen it is desired to beat a carpet, the brace 26 is lifted out ofthe notch 7 27, and when the beateris pushed forwardly,

by a forward push upon the handlel, it rides upon the upper surface of the plate 4 until said plate is in its-most forward position when said brace drops or can be manually pushed into a downward position out of locking engagement. Upon pushing the handle 1 forward, the platest and 5 will be rocked to move the gears 14in meshing en gagement-with the teeth 15 of the rotary sec 7 tions of the Wheels 7 and 8, and thus therotlie crank shaftz22. During-the rotation of the crank shaft 22, the operating ends 7 of, the various pivotally mounted heaters will .be' successively engaged by thG'I'OIlQIS 30 mounted upon-the: wrist of the crank shaftand depressed against the contracting action o'fthe' springs 37, raising the beating ends 35 thereof upwardly out of engagement with thecarpet or rug and after the rollers 30 pass off'the terminals of the operating ends 31 of the heaters, the respective springs 37 will contract, operating the heaters upon their pivots and bringing the heating ends 35 thereof into engagement with the carpet, rug or the like with a sharp quick movement effectively beating the same.

Changes in details may be made-without departing from the spirit of this invention, but; 2' 3 Iclaim: Y 7
